"Trojan:Win32/Skeeyah.l" detect from cryptography

[jp-nerdery]

I'm using windows server 2016 and running Windows Defender service.
I try to install cryptography using pip.
but Windows Defender delete "cffi_cffi_backend.cp36-win_amd64.pyd" everytime.
Dedenfer's deleting reason is "Trojan:Win32/Skeeyah.l" detect from cryptography sources.

cryptography is included malware? is really safe?

That is actually a native library compiled for the cffi package and not cryptography, although we depend on cffi so that's why it's installing during your pip command. That file is definitely not malware and is a critical component of the library. Windows Defender is evidently returning a false positive. I'd suggest reporting this to Microsoft, although I'm not sure how.

I understood that this problem is not caused by cryptography.
I will send report to Microsoft.below url.
